Plumbing a surface
1. Position tool close to the surface to
be plumbed.
2. Turn on tool.
3. Measure distance A at a point relatively
close to tool and make a note of
the distance.
4. Measure distance B at a point further
away from tool and make a note of
the distance.
Note: The greater the distance between the
two points of measurement, the greater
the accuracy.
5. Compare distance A with distance B. If
distance A equals distance B, then the
surface is plumb. If distance A does not
equal distance B, then the surface is not
plumb and should be corrected.
Plumb
Transferring points with the plumb beam
1. Mark the point to be transferred (labeled
A in this illustration).
2. Use the Mounting accessory or a Tripod
to position the plumb down beam over
point A.
3. The plumb up beam will transfer this point
along a perfectly vertical axis to point B.
4. Mark point B.
Note: This process may be reversed.

Leveling
1. Adjust the height of tool using the
mounting accessory or a tripod so that
the horizontal beam hits a reference point
(labeled A in this illustration).
2. Rotate tool around its mounting axis to
position the front level beam at a point of
interest (labeled B in this illustration).
Note: It is possible to use the beam as a
leveling instrument without marking a line
through beam locations, however, some may
find it more satisfying to mark the beam
location at a variety of points and then create
a straight line through those points to
achieve a level line.

Grading
1. Position tool at the highest point of
the surface to be graded.
2. Turn tool on.
3. Measure distance A and make a note of
the distance.
4. Measure distance B at distance X away
from A and note these distances.
5. Slope = (B – A)/X
Note: To calculate Pitch, set X equal to 12".
